Cleaning Glass – Substances like dusts, oils and fingerprints must be removed from glass before it’s fired or they may be visible in the finished work. In this lesson you will learn how to clean glass properly to avoid problems caused by surface contamination.

Preparing Kiln Shelves – Hot glass will adhere to kiln shelves if not prevented by a separator. In this lesson you will learn how to use Bullseye Shelf Primer, an affordable and highly effective separator.

Dealing With Devitrification – A common phenomenon that many kilnformers encounter is devitrification. Devitrification, or devit, is the growth of crystalline structures on the surface of glass.

Recommended Annealing Cycle for Bullseye Glass – Save time and energy. Anneal thick slabs at 900 degrees. As of June 2009, Bullseye has changed its chart for annealing thick slabs. Specifically, the recommended anneal soak temperature has been lowered from 960°F/516°C to 900°F/482°C.

Working With Powders on Sheet Glass – Firing crushed glass powders on sheet glass allows one a direct method to create imagery, pattern and nuanced shifts in value and hue. In this lesson you will learn about the tools and techniques involved and will get a broad overview of the ways glass powder can be used in art and design.

Pattern Bar: Segment Slabs – A segment slab is a multicolored glass block used in one approach to the pattern bar technique. The segment slab is composed of sheet glass strips that are tack-fused together, cut into parts, and fired within a containment system until the glass flows and forms an internal pattern.

Linear Reaction Plate – Step-by-step project demonstrating basic plate-making and glass-cutting principles and how special colours and effects can be achieved.

Clifford Rainey: In the Beginning Was Black – Artist Clifford Rainey explores the concept, purpose, reason, and processes employed to formulate the works in his solo exhibition In the Beginning Was Black, displayed at Bullseye Gallery September 4 to November 2, 2013. Rainey’s starting point for the new work is the human experience of loss. Combining this with the physicality of the color black sparked his investigation into the symbolism and the visual elements of this dark dense matter.

Artist Talk: Crystal Schenk – In this artist talk, Portland, Oregon–based artist Crystal Schenk discusses her current and past sculptures, and how she weaves memory, loss, and fragility throughout her artwork. She also talks about her large-scale stained glass work, Shelter, which was exhibited at Bullseye Gallery from November 6 – December 28, 2013. This project continues a prior theme in her work, examining the increasing gulf between the lower and upper classes – applying the perceived visual materials of the upper class to a very impoverished way of life as a way of pointing out disparity.
